Don't set them to empty at the bottom of the file. Do it right after the
INSERT to the database, and put the FORM below that.
An unfair restaurant-recommendation script:
<?php
$message = '';
# Horribly insecure code for illustrative purposes only:
if (isset($name) && trim($name) && $name != "McDonalds"){
mysql_query("insert into restaurants(name) values('$name')") or
die(mysql_error());
Blank out name for a new entry if they succeeded:
if (!mysql_errno()){
$name = '';
}
}
elseif ($name == "McDonalds"){
$message .= "We don't allow McDonalds to be recommened.<BR>\n";
}
else{
$name = '';
}
?>
<FORM>
<INPUT NAME=name VALUE='<?php echo $name;?>'>
</FORM>

Subject: How to destroy a $variable
> Ok I have a form with a $PHP_SELF target, and I enter parts of the form
> when they enter information if something is wrong with their input. Now
> what I would like to do is destroy all the variables when the form is
> correct and posted, so that when the page comes back up again, I post a
> thank you message, and the form is blank. Just a thought.
> I tried setting strings to empty after data is submitted to the database
> like so $Age = ""; etc.... at the bottom of the file.

> Bounce some ideas of me. Thanks
